Transcription

1 chapter 1 Introduction, medicines classification and standard operating procedures Overview Upon completion of this chapter, you should be able to: understand the layout of this book and the broad contents of the different chapters describe the different categories of medicines classification use standard operating procedures (SOPs) and understand the role that they play within pharmacy. Introduction and overview Layout of this text The supply of medicines is a basic function of pharmacists and pharmacy technicians. With the advent of clinical pharmacy and the introduction of new roles for pharmacists, the content of pharmaceutical education has altered to reflect these additions. However, the supply of medicines remains a key component of the role of pharmacy within modern healthcare and, therefore, it is vital that all pharmacists and pharmacy technicians are competent in medicines supply. This text has been designed to guide the student pharmacist or pharmacy technician through the main stages involved in safe and effective medicines supply. The aim of the book is to provide student pharmacists with an additional supporting revision text to accompany the compulsory dispensing courses found in all MPharm programmes and to reinforce the concepts discussed in Applied Pharmaceutical Practice (Langley and Belcher, 2008). In addition, it will be of equal value for student pharmacy technicians during their educational courses. Chapters 1 10 are set out as follows: 1. A chapter overview box summarising the main points contained within the chapter. 2. An introduction and overview of the key material covered within the chapter. 1

2 2 Applied Pharmaceutical Practice KeyPoint 3. Where appropriate, a collection of worked examples (Chapters 1-7) to further aid understanding and to include details on suitable labelling and packaging. 4. A series of self-assessment questions which it is expected that the student would To gain the most from this text, it is suggested that the reader has access to either the print or online version of a recent copy of both the British National Formulary and the respective Drug Tariff for their country (England and Wales, Northern Ireland or Scotland). work through independently. The answers to the questions can be found at the end of the book (in Chapter 11). To guide the reader through the different topics relating to medicines supply, this book has been divided into a number of different chapters, which reflect the chapters of the parent volume (Applied Pharmaceutical Practice) and are as follows. Chapter 1 Introduction, medicines classification and SOPs Chapter 1 introduces the text and provides an outline of the key points behind medicines supply. It also covers the basic classification of medicines and the role of standard operating procedures. Chapter 2 NHS supply in the community 1: prescription forms and prescribing Chapter 2 provides an overview of medicines supply in the community. NHS prescription forms and the restrictions placed on different NHS prescribers in the community, including the role of the UK Drug Tariffs, are covered. Chapter 3 NHS supply in the community 2: prescribers and the dispensing process Chapter 3 discusses the different NHS prescribers within the community. Following on from this is an overview of the dispensing process which should be followed when supplying medicines against NHS prescription forms, along with a collection of worked examples. Chapter 4 NHS supply within hospitals Chapter 4 covers the supply of medicines via the NHS within hospitals. Chapter 5 Non-NHS supply Chapter 5 contains similar material to Chapters 2 and 3, focusing on non-nhs supply, including the supply of medication against private prescription forms and via oral and written requisitions.

3 Introduction, medicines classification and SOPs 3 Chapter 6 Controlled drugs Chapter 6 uses some of the material already discussed in Chapters 2 5 and summarises the laws and regulations relating to the supply of controlled drugs, via both NHS and non-nhs routes. Chapter 7 Emergency supply Chapter 7 reinforces the key points behind the emergency supply of medicines by a pharmacist, at the request of both a prescriber and a patient. Chapter 8 Patient counselling and communication 1: the basics of patient communication Chapter 8 provides an overview of the basics of patient communication ensuring that pharmacists and pharmacy technicians are familiar with both verbal and non-verbal communication, and are able to communicate effectively with patients and carers. Chapter 9 Patient counselling and communication 2: product-specific counselling points Chapter 9 summarises important counselling points that need to be considered for specific dosage forms, and is a useful reference source to enable students to answer parts of the self-assessment questions from other chapters. Chapter 10 Poisons and spirits This chapter discusses the key points behind the supply of poisons and spirits from pharmacies. Chapter 11 Answers to self-assessment The final chapter contains answers to the exercises found in earlier chapters of the book. Medicines classification The Medicines Act 1968 defines three classes of medicinal products for human use: general sale list (GSL) medicines, pharmacy (P) medicines and prescriptiononly medicines (POMs). KeyPoints This revision text has been designed to provide student pharmacists and technicians with a supporting revision text to accompany the compulsory dispensing courses found in all MPharm and technician education programmes. To gain the most from this book, we suggest using the examples contained within it alongside the parent volume, Applied Pharmaceutical Practice (Langley and Belcher, 2008), which goes into more detail about the topics summarised in the chapters in this text. The Medicines Act 1968 defines three classes of medicinal products for human use: KeyPoints general sale list (GSL) medicines pharmacy (P) medicines prescription-only medicines (POMs).

4 4 Applied Pharmaceutical Practice KeyPoints General sale list medicines These are medicines that can be purchased from a wide range of shops, general stores, supermarkets, newsagents, petrol stations, etc. Products classified as GSL are considered to be reasonably safe and therefore can be sold without the supervision of a pharmacist. Products categorised as GSL medicines have strict controls concerning their strength, use, pharmaceutical form and route of administration. The maximum dose or maximum daily dose is also controlled for medicines for internal use. Another control that may be enforced is pack size with a limit to the size of pack allowed as a GSL medicine. The following classes of medicinal products for human use are not allowed to be classified as GSL medicines: enemas eye drops eye ointments products containing aspirin or aloxiprin and intended for administration either wholly or mainly to children products for parenteral administration (a product given by injection, bypassing the enteral (gastrointestinal) tract) products used as anthelmintics (a substance that expels or destroys intestinal worms) products used for irrigation of wounds, the bladder, vagina or rectum. Pharmacy medicines can be sold only from a pharmacy under the supervision of a pharmacist. It should be noted that, although the sale of GSL medicines from a pharmacy does not need to be under the supervision of a pharmacist, GSL medicines must still be sold under the personal control of a pharmacist. The term personal control comes from General sale list (GSL) medicines are medicines that can be purchased from a wide range of shops, general stores, supermarkets, newsagents, petrol stations, etc. Products classified as GSL are considered to be reasonably safe and therefore can be sold without the supervision of a pharmacist. the Medicines Act 1968 and has never been interpreted in the courts. However, it is generally understood to mean that the pharmacist must be available on the premises. If a pharmacist is not available, no medicines (including GSL items) may be sold at all. For this reason, GSL medicines sold from pharmacies are often treated as P medicines. Obviously, this restriction does not apply to GSL medicines sold from other (non-pharmacy) establishments. Pharmacy medicines These may be sold from pharmacies under the supervision of a pharmacist. The pharmacist or the pharmacy technician/ counter assistant asks a number of questions before making the

5 Introduction, medicines classification and SOPs 5 sale to ensure that the medication is safe for the patient and advice as to the use of the product is provided. Some medicines may be sold only when certain criteria have been met, e.g. when supplying emergency hormonal contraception from a community pharmacy. A P medicine is the definition given to medicinal products not included on the prescription-only medicines order or Pharmacy (P) medicines may be the general sale list or is a product that is sold from pharmacies under the supervision of a pharmacist. supplied outside the GSL package limit or maximum dosage limit. A few medicines are called pharmacy-only (PO) medicines and include medicines that would normally be included on the GSL list but where the manufacturer has limited the supply of the medicines to pharmacies only. Prescription-only medicines These medicines are usually obtained on the authorisation of a valid prescription form (either an NHS or a private prescription form), written by a recognised prescriber registered in the UK and presented at a registered pharmacy (although exceptions to this do exist, e.g. dispensing doctors, inpatient hospital supply and emergency supply at the request of a patient). Traditionally the prescriber would have been a doctor or a dentist but, with recent changes to healthcare legislation and the introduction of supplementary and independent prescribers, the term prescriber includes many other healthcare professionals such as suitably qualified nurses and pharmacists. Medicines may also be exempted from POM classification if there are limitations on the use of the product. An example would be hydrocortisone cream 1% normally categorised as POM, but a P medicine in packaging that limits the use of the cream to the treatment of allergic contact dermatitis, irritant dermatitis, insect bite reactions and mild-to-moderate eczema; it should be applied sparingly once or twice a day for a maximum of 1 week. The P or over-thecounter (OTC) form is licensed only for those indications and dosages, and further restriction to sales include unsuitability for OTC sale to treat: children under 10 years conditions on the face or anogenital area KeyPoint KeyPoints Prescription-only medicines (POMs) are medicines that are described in the Prescription Only Medicines (Human Use) Order They are usually obtained on the authorisation of a valid prescription form (either an NHS or a private prescription form) written by a recognised prescriber registered in the UK, presented at a registered pharmacy (although there are exceptions). Traditionally the prescriber would have been a doctor or a dentist but, with recent changes to healthcare legislation and the introduction of supplementary and independent prescribers, the term prescriber includes many other healthcare professionals such as suitably qualified nurses and pharmacists.

Medicines containing controlled drugs are generally given a POM classification. Exemptions to this general rule include where the strength of the controlled drug included in the medication is below a certain value and when the medicine ingredient is covered by Schedule 5 of the Misuse of Drugs Regulations Standard operating procedures Standard operating procedures are often referred to as SOPs and include all the Standard operating procedures written protocols and procedures in place are often referred to as SOPs and within a pharmacy. They state the way that include all the written protocols the pharmacy expects tasks to be carried out and procedures in place within a pharmacy. to ensure provision of a quality service. They include, for example, the questions that must be asked of a patient so that his or her needs can be correctly identified and appropriate action taken. The history of SOPs Standard operating procedures, in their current form, have existed for the dispensing supply process since January They were put in place to ensure clinical governance of the dispensing procedure. Clinical governance is the term used in the National Health Service (NHS) and private healthcare system to describe a systematic approach to maintaining and improving the quality of patient care. As pharmacies differ so much, a single SOP could not be devised that would cover all pharmacies. Therefore each pharmacy has individually tailored SOPs for their working environment. Larger companies, with numerous pharmacies, may have single SOPs that cover all their premises. These were formerly known as company policy. It is considered good practice to have SOPs in place for all procedures carried out in the pharmacy. What are the advantages of SOPs? 1. They can assist with quality assurance, ensuring that patients receive a service that meets certain predefined standards. 2. They ensure consistency, which helps to maintain the level of service offered and therefore maintain good pharmaceutical practice at all times. 3. They help free time for pharmacists, by enabling the delegation of certain tasks. This in turn enables pharmacists

7 Introduction, medicines classification and SOPs 7 to engage in some of the new roles and provides enhanced roles for pharmacy technicians that recognise their specific expertise. 4. They set out clear lines of accountability, ensuring that staff are aware of their own responsibilities. 5. They help locum and part-time staff understand the processes and running of the pharmacy. 6. They are useful templates in the training of new staff. 7. They provide additional information for the audit process. The preparation of SOPs The Royal Pharmaceutical Society of Great Britain (RPSGB) broke down the preparation of an SOP into six stages: 1. Objectives: the purpose of the SOP. 2. Scope: what are the areas of work to be covered by the SOP? It is advisable that this should not be over-complex. 3. The stages of the process: this is a description of how the task is carried out. It is important that this description is clear and unambiguous, preferably without the use of jargon. 4. Responsibility: who is responsible for carrying out the procedure and who ensures that staff members are suitably trained to carry out a procedure? In a working pharmacy this would also include contingency plans detailing what to do in cases of sickness or holiday leave, etc. 5. Other useful information: for example, details on how the SOP is to be audited. Auditing the processes helps maintain standards and identifies any areas where improvement could be made. 6. Review: shows how the process is monitored to ensure that it remains up to date and relevant. The pharmacy contract for England and Wales The pharmacy contract divides the activities that community pharmacies undertake into three tiers of service: essential services, advanced services and enhanced services. The essential services provided by a community pharmacy are compulsory and the minimum required of a contractor as part of the pharmacy contract. There are now eight essential services identified in the contract: 1. Dispensing 2. Repeat dispensing 3. Stoma and incontinence services 4. Disposal of unwanted medicines 5. Promotion of healthy lifestyles (public health) 6. Signposting (provision of information on where and how to access other healthcare and social care providers)

8 8 Applied Pharmaceutical Practice 7. Support for self-care (help to minimise the inappropriate use of healthcare and social care services) 8. Clinical governance (this has been strengthened and built on since October 2011, including the requirement for a whistleblowing policy to ensure high standards are maintained). A similar contract exists within Scotland, with four core services: an acute medication service (AMS), a minor ailment service (MAS), a chronic medication service (CMS) and a public health service (PHS). Additional services are to be agreed locally but on the basis of national (Scottish) specifications. A pharmacy must have in place SOPs for all these activities. In addition other SOPs are developed to aid the business, e.g. an SOP covering OTC sales (sale of medicines and provision of advice), stock ordering and receipt of goods (ensuring that stock received is what was ordered, is in date and does not have a short shelf-life, and is to be stored correctly) and the receipt of telephone calls, should be in place In addition to essential services pharmacies are also engaged in a number of service developments as advanced services. These are designed to utilise better the expertise available in community pharmacies, thus making better use of resources within the NHS, providing value for money for the NHS. The first advanced service was the Medicines Use Review (MUR) and prescription intervention service. This is designed to help patients taking multiple medicines, especially those receiving medicines for long-term conditions. The MUR process is designed to ascertain patients use of their medicines, both prescribed and non-prescribed, identify any problems they may have concerning their medicines and offer possible solutions, resulting in improved adherence to the treatment regime. This process has been successful and, as of October 2011, in addition to general MURs for patients there will be national target groups: patients taking high-risk medications (as identified in the National List) patients recently discharged from hospital who have had changes made to their medication while they were inpatients patients with respiratory disease. It is anticipated that further target groups will be identified. The second advanced service to be introduced to the NHS Community Pharmacy contract was Appliance Use Review (AUR). The AUR is similar to the MUR; its aim is to ensure that patients are using appliances correctly. The AUR identifies any problems or ineffective use of an appliance and resolves any issues raised, including advice on the storage and disposal of appliances.

9 Introduction, medicines classification and SOPs 9 The third advanced service introduced was Stoma Appliance Customisation (SAC), which is a service offered in the main by specialist appliance contractors and not local community pharmacies. A fourth new advanced service, introduced in October 2011, is the New Medicines Service. This service will provide support for patients with long-term conditions who have been newly prescribed a medicine. It is hoped that this will help to improve patient adherence and generally lead to better health outcomes. This is a time-limited service, funded until March 2013, but will continue past this date if the service can be shown to provide value for money for the NHS. Initially it will be aimed at particular patient groups and conditions: antiplatelet/anticoagulant therapy asthma or chronic obstructive pulmonary disease type 2 diabetes hypertension. Patients can be offered this new service when they bring a prescription for a new medicine to their pharmacy or they may be referred to the service by prescribers. The third tier of services offered by community pharmacies is termed enhanced or localised services and these are funded locally. These services are commissioned when local need is identified. Examples of these services include: emergency hormonal contraception services needle exchange schemes NHS health checks (vascular risk assessment) smoking cessation clinics supervised administration (consumption of prescribed medicines) weight management clinics. This list is not exhaustive and other identified needs will be added in different localities. However it is clear that the NHS contract for community pharmacy is changing to utilise skills of pharmacists better. Further updates and changes to the community pharmacy contract can be found on the Pharmaceutical Services Negotiating Committee website ( Worked examples Example 1.1 An SOP for the reception of a prescription form within a community pharmacy A summary of how to dispense NHS and non-nhs prescriptions can be found in the subsequent chapters of this book. However, consider an SOP for the dispensing of prescriptions (i.e. service

This can be broken down into a number of stages: 1. Prescription reception 2. Professional check 3. Intervention and problem solving 4. Label generation and collection of prescription item(s) 5. Accuracy checking 6. Handing out prescription item(s) to patients or their representatives 7. Dealing with owings when prescription forms are incompletely filled. The list above covers the basic dispensing procedure and each stage requires an SOP. Figure 1.1 contains an example of an SOP for the reception of a prescription form within a community pharmacy.

Summary This chapter has introduced the text and explained the contents of the subsequent chapters. In addition, basic medicines classification has been described, where medicines are classified into three categories: GSL medicines, P medicines and POMs. Finally, the purpose and construction of SOPs have been covered. It is important that student pharmacists and pharmacy technicians understand the points covered in this chapter and attempt the questions at the end of the chapter before moving on to any subsequent parts of the book.
